victorParticipantHi, it’s me E.anythingus…as a soon-to-be-microbiologist, I wanna held a test for all of you..huahahaha..enjoy it..it’s about virology. Don’t cheat dear.. 😆
give a brief explaination of: (V = virus)
EBV, HIV, CMV, SIV, ArboV, MyxoV, RetroV, PaPoVa-V. - January 20, 2006 at 6:26 pm #37912MrMisteryParticipant
What’s in it for me?
- January 20, 2006 at 6:32 pm #37916SquawkboxParticipant
is it the 22nd letter in a geek childs alphabet wall chart:?:
A=anatomy
B=bacteria
C=clostridium
D=diaphragm
E=E. Coli
etc etc etc
V=virus
etc etc etc - January 20, 2006 at 9:46 pm #37935mithParticipant
lol I only know retro, uses rna template to convert to dna
- January 20, 2006 at 9:53 pm #37936canalonParticipant
EBV=Epstein-Barr Virus cause Infectious Mononucleosis
HIV= Human Immunodeficiency Virus cause AIDS
CMV= Cytomegalo Virus, no idea what it does 🙂
SIV= Simian Immunodeficiency Virus cause AIDS in apes
ArboV= ArboVirus or viridae, a family of virus
MyxoV= Myxovirus another family
RetroV= Retrovirus…
PaPoVaV=No ideaWithout even googling…
- January 21, 2006 at 11:51 am #37964jnkdnaParticipant
i dont know any except for human immuno deficiency virus!!!!

Wow..cool !!!
by the way, PaPoVa virus consists of three viruses.. 😆
it’s Human Papilloma Virus, Rabbit Polyoma Virus and Simian Vacuolating agent..tricky eh?? 😆 - January 22, 2006 at 2:12 am #38025canalonParticipantquote victor:Wow..cool !!!

But can you explain us why the PaPoVa are grouped together? - January 22, 2006 at 11:58 am #38065opuntiaParticipant
Do they all cause the same disease? 😕 😕
- January 22, 2006 at 12:01 pm #38067jnkdnaParticipant
i dont think they all cause the same disease but im pretty sure they are all connected some how!
but then again it makes more sense if they cause the same disease. y else would they be grouped together!! - January 22, 2006 at 12:08 pm #38071victorParticipantquote Canalon:quote victor:Wow..cool !!!

But can you explain us why the PaPoVa are grouped together?it’s because three of them (like previously said by Opuntia) make the same dissease which is "crabs"… 😆
Oh, forgot something Doc…Cytomegalo virus is just like the name causing Cytomegalic condition inside the cell…
- January 22, 2006 at 12:19 pm #38075opuntiaParticipant
And "crabs" mean cancer?
- January 22, 2006 at 12:24 pm #38076Dr.SteinParticipantquote opuntia:And “crabs” mean cancer?
😆 I already know this joke but I still can’t stop laughing everytime I remember 😆
I think I came late to the test, means that I do not necessary to do them eh? 🙂
- January 22, 2006 at 12:30 pm #38082opuntiaParticipant
Since you are too late that means you won’t get any marks, right, Sir Victor? 😆
- January 22, 2006 at 12:37 pm #38088victorParticipant
Okay..I’ll give the late person a makeup test… 😆
which of these virus family that cause dissease named chicken pox??
a. Hepadnaviridae
b. Retroviridae
c. Herpesviridae
d. Poxviridae
e. Adenoviridae - January 22, 2006 at 12:44 pm #38093opuntiaParticipant
c is the correct answer!
- January 22, 2006 at 12:50 pm #38097victorParticipant
Yo…you’re right fella…:lol:
and now, for a lil bit hard one..
HIV have a +sense RNA that can act as mRNA for protein translation…but in the replication process, it doesn’t do that…explain why and describe the pathway it use.. - January 22, 2006 at 12:55 pm #38099opuntiaParticipant
That’s too tough for me…coz i haven’t studied that yet, so i give up for now but will come up with the answer when i learn them 😀
PS: has it got anything to with the virus having reverse transcriptase?
- January 22, 2006 at 1:12 pm #38109victorParticipant
actually you can answer it…just see the picture of HIV in my signature…it helps you a lot…
a clue: +sense RNA virus that use it’s RNA as mRNA can be classifid into ssRNA (single stranded RNA, or in other words, haploid RNA)…happy answering..:lol: - January 24, 2006 at 3:59 pm #38316NiteParticipant
ds DNA is formed from the +RNA by reverse transcriptase. The ds DNA is then incorporated into the host chromosomal DNA and the virus enters lysogeny cycle.
It’s a characteristic of retrovirus as u mention before?
why it does so? guess it does that so that it can be incorporated into the host DNA?
hehe. i just had a lecture about HIV today 😀 .
i m a newbie in virology 😳btw, wad does GAG and GP in the HIV diagram stand for?
- January 25, 2006 at 11:31 am #38387victorParticipant
Yup, that’s the "common" characteristics of retroviruses….why I call it common??because there’re three subfamilies of retroviruses: Oncovirus, Lentivirus and …..virus..(argh, I forgot the name)..poor me.. 🙁
Why it does so? because according to Baltimore virus’ classification, retroviridae is classified into dsRNA with DNA intermediate (reverse transcriptase) which has a diploid RNA attached to reverse transcriptase enzyme for each of them….and also, in order to do capsid "uncoating", they have to do so..
gag is a code for virion’s protein construction.
gp = glycoprotein… 😆 so, gp120 = glycoprotein code 120…
easy isn’t it.. 😆
don’t say like that Nite, because I’m also a newbie in Virology and now, I’m learning for the next virus which is Herpesvirus.. 😀 - January 26, 2006 at 9:35 am #38525victorParticipant
And now, for the next question..:lol:
I’ve just read about EBV or in other words every body’s virus..:lol: (it’s real name).
Now, if EBV crates Lymphoblastoma on B-cell and affecting of excesses IgM antibody secretion, then why it’s said than EBV is harmful for us?? more antibody is better isn’t it??:lol: - January 26, 2006 at 12:18 pm #38537Dr.SteinParticipant
Naah. The excessive IgM and IgG is because of the excessive VCA/EBV/EBNA. You know the immune response… If you want to get those immunoglobulins for more, ok ok I will inject you with more EBV, agree? 😆 Maybe you want to experience how is the feeling of suffering mononucleosis, Burkitt’s lymphoma and nasopharyngeal carcinoma. Come to me my dear, I still have some vials of EBV mwahahahaa 😈 😆
- February 2, 2006 at 12:14 pm #39318victorParticipant
the answer is excessive on IgM can cause erythrocyte aglutination..hahaha..and beside, the infected B-cell secretes an IL-10 like protein that cause inhibition of IFN-gamma secreation in T-cell and NK-cell..

a. Hepadnaviridae
b. Retroviridae
c. Herpesviridae
d. Poxviridae
e. AdenoviridaeC is the correct answer. The varicella-zoster virus to be exact one of 8 herpes virus I think.
- February 18, 2006 at 12:08 pm #41213victorParticipant
Ok, let’s head for the next question: 😆
how many classification based on virus’ capsid structures?? - February 20, 2006 at 10:50 am #41348Dr.SteinParticipant
*yaaawn* 😳
- February 21, 2006 at 12:25 pm #41473victorParticipant
why boss? you look so sleepy in this question??:lol: is it because you’ve just come back from Jakarta…:lol:
- February 22, 2006 at 9:24 am #41532Dr.SteinParticipant
Hehe you know that 😳 😉 I visited Mr.Stein 😛
I remember a subject in our faculty: Systematics of Microbes, I am sure you will take it when your time comes 😉 - February 23, 2006 at 6:28 am #41590victorParticipant
Unfortunately…you guess it wrong boss…I don’t really like taxonomy..
Ok, the answer is:
there are 3 types which are symetry icosahedral, sphrical and complex structure…:lol: - February 24, 2006 at 3:41 am #41676Dr.SteinParticipant
You should know that there is a principle difference between "systematics" and "taxonomy" 😉 You will see the difference soon 🙂
- February 25, 2006 at 11:46 am #41756victorParticipant
I hope I can pass it with a good score…:lol:
Next:
Based on those three types of virus structure, now what structure that TMV and bacteriophage bears?? - March 2, 2006 at 6:45 am #42132damien jamesParticipant
Victor, you’re going to be a microbiologist too? Cool! I graduate this year with degree in microbio, but only undergrad :(. Do you know where you’re going to work yet?
- March 2, 2006 at 12:39 pm #42163
- March 6, 2006 at 7:58 pm #42577JimmyCParticipant
Dear Victor, I’m pretty sure your little quote is bollocks as in an endothermic reaction u could just put more heat in or maybe if there are less moles of product produced than reactants put in then u could also up the pressure to get a higher yield!
- August 13, 2006 at 4:37 pm #53298opuntiaParticipantquote victor:I hope I can pass it with a good score…:lol:
Next:
Based on those three types of virus structure, now what structure that TMV and bacteriophage bears??Am i late for the class? i hope not
TMV=Spherical
Bacteriophage=IcosahedralNot so sure about the phage…could be because i always hate microbiology so very much! 😆 😆
- August 14, 2006 at 8:06 am #53334victorParticipant
They’re complex…:lol:
Hey, this post has overdrowned I think.. 😆 - August 16, 2006 at 6:31 pm #53508opuntiaParticipant
Yeah, I’m trying to bring this alive again coz next semester i’ll be studying microbiology and i’m a real dope at it.
- August 19, 2006 at 11:44 am #53626victorParticipant
Hmm..I can think that MicBio is very interesting…because it’s a chance in a lifetime you’re given to observe thos tini creatures… 😆
